AUTO PULL-OUT.

Specification of Letters Patent. Patented J 11119 15, 1920.

Application filed January 29, 1918, Serial No. 214,389. Renewed April 28, 1920. Serial No. 77,420.

To all whom it may concern:

Be it known that I, LOUIS HAMMER, a citizen of the Dominion of Canada, residing at Olds, in the Province of Alberta, Canada, have invented a new and Improved Auto Pull-Out, of which the following is a specification.

My invention has reference to improvements in means adapted to be readily applied to the conventional types of automobile chassis andcapable of being quickly adjusted for utilizing the motor engine for pulling the vehicle out of ruts, mud, holes, etc.

More especially my present invention has reference to that type of pull outs in which is included a drum on which the anchored or pull cable is wound, for example,

as illustrated in my Patent No. 1,256,791, dated February 19, 1918.

Among other objects, my present invention seeks to provide a mechanism for the purposes stated of a simple and inexpensive construction, in which the parts are individually designed and adapted to be so combined that the said mechanism may be quickly applied to the chassis of all of the ordinary types of motor vehicles, capable of being instantaneously adjusted into a clutched engagement with the vehicle motor shaft or released from such shaft and which serves its intended purposes in a thorough, practical and efficient manner. Again, in my present invention, I have provided an improved power transmission for driving the cable wind-up with adjustable means for holding the said transmission to the driving position for applying the desired power to the cable wind-up devices and which can be quickly shifted for permitting the removal of the said transmission and the substitution therefor of a direct drive shaft section carrying a belt or chain pull for coupling a drive or chain belt therewith for transmitting the power for running such light machinerythat constitute parts of modern farm equipment. Another and important feature of my present invention lies in the improved construction of the power transmission devices, including adirect driving connection with a jack shaft and shiftable gearing on the jack shaft adapted to be freely shifted into engagement with the winding drum when it is desired to wind up the pull cable and for being moved out of mesh with the said drum to permit of the free rotation of the drum when playmg out the cable therefrom, for attaching it to an anchor post.

lVith the above and other minor objects in view, that will hereinafter appear, my present invention is an improved auto pull out mechanism that embodies the peculiar features of construction and novel combination of parts fully set out in the following description and specifically stated in the ap pended claims and as illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of my present construction of pull out mechanism, the parts being in the operative position, a cranking lever being indicated as an applied portion thereof, in dotted lines.

Fig. 2 is a longitudinal section thereof on the line 2-2 of Fig. 1, the said mechanism being shown as in a coupled position with the engine shaft for driving the cable carrying drum.

Fig. 3 is a planrview of my present in vention, the worm or transmission shaft being shown out of clutch with the engine shaft, and the jack shaft as uncoupled from the winding drum, the latter being now free to permit of pulling out the cable for making the anchor connection, the hinged cap that closes over the transmission worm gear being shown as raised.

Fig. 1 is an end view of the transmission shaft, the gear that connects said shaft and the jack shaft and the casing that constitutes a support for the transmission shaft,

Fig. 5 is a transverse section taken on the line 5-5 of Fig. l, of one of the end brackets that connects with the chassis and in which one of the outer ends of the drum and the jack shafts journal, the said bracket being shown in side elevation.

Fig. 6 is a detail perspective view of one of the said brackets.

Fig. 7 is a diagrammatic plan view that pear.

' illustrates a supplemental transmission shaft,

with a transmission power pulley, the said shaft forming a substitute for the worm transmissionshaft when it is desired to utilize the motor shaft for driving wood sawing or other like machinery.

Referring now more particularly to Figs.

hanger members 23-2%l that are braced by a connecting web 25 and the said bracket members 23 each have a bearing aperture 26 and the members 24: a vertically elongated slot 27, the purpose of which will presently ap- In my patented structure above referred to, the cable winding means includes a shaft centrally equipped with a driving gear that meshes directlywith the worm on the trans mission shaft and two drum sectionskeyed upon the said shaft.

In my present construction, 1 use but a single drum 3 that extends practically the full width between the opposite chassis members 1-1 and it is loosely mounted on a shaft a whose opposite ends journal in the bearing apertures 26 in the bracket members 23.

Each end of the drum has keyed, or otherwisefixedly attached thereto, a gear By using a single drum, as shown, a long length of pull cable may he carried thereon, it being understood that the inner end of such cable, in practice, is made fast to the drum and further by loosely mounting the cable drum on the shaft, when the said drum is freed from connect on with the power tiZLIlSIIllSSIOD, as will be presently more fully understood, the outer or free end of the pull cable may be readily played out from the drum when it is desired to anchor the cable without disturbing any of the other parts thatconstitute my present invention. 7

7 designates a jack shaft 111 parallelism with and disposed to the rear of the drum shaft and is best shown in Figs. 2 and 5, by reference to whichlt will be seen that the I opposite ends of the jack shaft 7 arejournaled in bearing boxes 8 8 mounted in each of the slots 27 of the bracket hangers 24 and the said boxes 8 have vertical adjustment in said slots 27 and are heldto their adjusted positions by clamp screws 28-28, as shown. 1

In my present construction, the shiftable transmission devices, when coupled with the engine shaft, instead of being geared directly with the drum shaft, as in my patented structure above referred to, are arranged .for transmitting an indirect and increased power to the said drum shaft and to such end the transmission shaft section 5 is loosely .journaled in the ends -60 of the housing or casting which is best shown in Figs. 1,2 and 3.

The casting or housing 6 is formed with pendent side brackets 6161 that'are supported on the jack shaft 7 which passes through apertures 62-62 in the said brackets.

The casting 6 also has apertured ears 63-63 at one side connected by a hinged pintle 64: to which a housing or cover 65 is hinged for 'beingswung to-the vertical position shown inFig. 4. When placingthe transmission shaft section 5 into or removing it from the operative position, the cover 65, when the parts are operatively assembled, is held to the closed position by screws 66 that engage registering apertured ears on the cover and the housing body.

The worm gear, in my present structure, is'keyed to the shaft 5 to turn therewith and it meshes with and transmits motion to a gear 70 keyed to the jack shaft 7 and the said motion is transmitted to the drum shaft through the gears 71-71 on the opposite ends of the jack shaft 7 hereinbefore referred to and which are made fast to the shaft by clamp screws 62-72 that take through the gear hubs 73-73.

The, gears 71-71, when the parts are in the operative or cable wound-up adjustment, mesh with the drum gears 30'30, as

shown in Fig. 1. hen, however, it is de sired to pull the cable from the drum for anchoring, the gears. 71-71 are shiftedto the position shown in Fig.6. 7

11--11 designate brace rods that connect with the chassis members 1-1 and the opposite sides of thehousing 6.

12 indicates a slotted clutch sleeveon the outer end of the engine shaft 9. 13 indicates the usual clutch pin and 55 the slot in the end ,of the transmission shaft which engages the said sleeve and the pin when the shaft is slid back and clutched'with the engine shaft, as shown in Figs. 1 and-2.

In my present construction of pullout mechanism, a lever 14: is pivoted at oneend on a bracket 66 on the housing 6,. and the said lever straddles and engages the annular groove 15 of a disk fixedly connected to the shaft and whose front end terminates in a ratchet face 15*. V v

, For shifting the transmission shaft into a clutched engagement with the engine shaft, the lever 14 is adjusted to thepositio'n shownin 1 and for throwing the transmission mechanismout of engagement with the engine shaft, the said lever is swung out in the position shown in Fig. 3.

'17 designates a crankinglever indicated in dotted lines in Fig. 1 whoseinner end has a ratchet surface for coupling with the ratchet 15 on the disk 15.

From the foregoing description, taken in connection with the drawings, the complete construction, the manner of its use and the advantages of my improved pull out mechanism will be readily apparent.

lVhen attached to motor vehicles having selfstarters, the adjustment of the lever 14: to the position shown in Figs. 1 and 3 provides for putting the pull out mechanism into or out of operative connection with the engine shaft, the crank lever being utilized when the attachment is secured to machines that are not self-starters.

It will be noticed by referring to Figs. 2 and 3, there is sufficient play in the housing 6 for shifting the shaft 5 with its gear to the clutching and released positions and when shifted to the clutch position the con nection of the gears 50 and is such that so long as the engine is running, the gear 50 will be held up to the active or clutched position shown in Fig. 1.

When it is desired to use the vehicle motor for farm work, that is,-driving small machinery-the transmission shaft 5 is removed and a plain shaft 18, shown in Fig. 7, is substituted therefor, and when the latter is used a trai'isverse front bearing bar 80 is attached to the opposite chassis members 11.

In practice, a hood m covers the working parts of my pull out mechanism and the latter is hingedly attached to the front of the radiator hood, as indicated in dotted lines in Fig. 5.
